Renewed May 23, 1935 9 Glaimst (01. 189-72) This invention relates towindow construction,

an object ofthe invention being to provide a win dow construction havingsliding sashes, the latter having roller contact with the frame, saidcontact being adjustable so as to ensure an easy movement and yetprovide a tight sash.

A further object is to provide, in combination with the roller sash,improved resilient weather strips with which the sashes contact.

A further object is to provide an improved frame construction with aremovable section providing access to the weight boxes.

A further object is to provide a window construction having an improvedarrangement of parting strip and inner bead, both of which are removableto facilitate the assemblage of the sashes in the frame or'r'emoval ofthe sash there provided at its bottom or lower end with angular anchorpieces for fastening the sill to the channel frame, and the uppercorners of the channel.

frame are riveted or welded together and create an'unusual, strongconstruction upon which masonry may lie and serve instead of a lintel.

A further object is to provide a window construction of this characterembodying many novelfeatures of construction and combinations andarrangement of parts, all of which will be more fully hereinafterdescribed and pointed out in the claims.

Figure 9 is a fragmentary sectional plan view of the lower sash.

Our improved window construction embodies a heavy gauge channel-shapedbuck illustrated generally'by the reference character I, which islocated around three sides of the window opening; that is to say, at thetop and at both sides of the opening. This buck constitutes weight boxesand spaces for the necessary pulleys and the like for supporting thesashes, and may be of steel or other metal. The lower ends of the buckreceive therein anchor pieces 3, the latter'having upright flanges 4 towhich in-turned flanges 8 on the buck are secured. These flanges 8 arepreferably turned backward on themselves for strength and for rigidityof coupling. Non-ferrous frame members 5; are secured to the anchorpieces 3 and close the open portions of the channel-shaped buck l. Theanchor pieces 3 also serve to secure the buck and frameto a sill I sothat the buck, sill and frame members constitute a strong, rigidstructure which may be inserted in the window opening. The side membersof the buck l which form weight boxes have removable and swingingpartitions 9 therein which are hung from the top and which can bereadily moved so that access may be had to both compartments through asingle entrance, as will more fully hereinafter appear. An upper memberll) is also fixed to the upright side members 5 and to the lintelportion of the buck to complete the frame structure, and plates lllocated at proper intervals are secured to the weight boxes and lintelformed by the buck l and to the masonry or wall construction.

The vertical side members 5 of the frame are made with integral outerbeads l2 comprising an inverted three-sided channel shaped member andwith seats for a removable inner bead l3 and a removable parting stripit. The parting stripl t has a plate It extending throughout the lengthof the frame, forming with the strip Mi a member T-shaped in crosssection, each end of the T head it comprising a bearing surface havingsealing engagement with the upper and lower sashes A and B. The strip Ithas flanges it at its edges which co-operate with shoulders H which formthe parting strip recess on the frame member and on a removable sectionit of the frame, to form holding means or confining means for the edgesof bowed Weather-strips i9 located at opposite sides of thepartingstrip. The weather strips I 9 are integral parts. of an element U-shapedin cross section. The*bottom of the U-shaped element fits between andisheld by the shoulders I! and the legs of the U-shaped element projectoutward from the Jamb member. The parting strip l4 may be removablysecured in place by means of screws 20 so that it may be strip "properlyengaging over an enlargement readily removed as occasion may require.The strip I 4 cooperates with the shoulders llto hold the weather-stripelement in place.

The inner bead II. constitutes a bar which has webs 2| fitting ingrooves 22 in the frame member '5 and in the removable section l5respectively, and this inner bead I 3 issecured to the frame member 5 bymeans of screws 23 so that it is readily removable on occasions. Theremovable section II of the frame member 5, which may be puncheddirectly out of the frame member and preferably extends for but a shortdistance of the length of the frame member, is held in closed positionby one of the webs 2! of the inner bead l3, and also by reason of thefact that this section I! has a stepped plate 24 fixed to its rear facewhich extends back of the strip l4, and screws 20 which hold the partingstrip l4 in place are also screwed into threaded openings 25 in thisplate 24 after being screwed to the frame bar 5.

Aand B represent the upper and lower sashes which are .mounted to slidein the frame between the beads i2 and i3 and the parting strip l4. Theupper horizontal bar 25 of the sash A has agrooved portion 21 receivinga web 28 on the bar I5, and the lower bar '25 of the lower sash B isprovided with webs 30 and II and a weather- 33 on the sill I. Meetingrail 34 of the upper sash A and meeting rail35 of the lower sash B areformed with inter-engaging webs 36 and 31. The rail 34, carries aweather strip 38 engaging the web 31, and a flange or web on the-bar 35engages the upper edge 01'- the bar 34 giving a three-point contact. Theconstruction of the three-point contacts between the bars of the sashand frame are illustrated in our United StatesPatent No. 2,084,355,dated June 23, 1937.

An important feature of this invention is the employment of rollers 40which are carried by the vertical-bars of both sashes which engage theouter bead l2, and by reason of the adjust ment of these rollers thefrictional sealing engagement between the webs 4l'on the rails and theresilient weather-strips I9 is regulated. Any desired number of theserollers 40 may be em-.

ployed, and each roller 40 issupported on a trunnion 42 projecting fromthe end of a plate 43, and the major portion of the roller is housedwithin the hollow vertical bars of the sash frames. The ends of theplates 43 are movably fulcrumed in notches 44 in the sash bars 45. Thetrunnions 42 move in slots 45 in the peripheral walls of the bars 45,and the rollers 40 project through slots 41 in the inner side wallsofthe bar and bear against the beads l2 and II respectively. Screws 45project through the openings 49in the bar 55 and have screw-threadedengagement with the plates 42 so that by adjusting these screws theangular disposition of the plates may be varied so as to force therollers with variable pressure against the,beads. The pressure exertedforces the web 4i, on the opposite side of the vertical sash'bars fromwhich the rollers 40 project, into sealing frictional engagement with.

surfaces at either side of the T head l5- to give a weather-tight andfreely movable -engagement between the sashes and the parts of theframe;

' Should it be necessary at any time to have access to the weight boxesthe inner bead I2 and the parting strip l4must be removed, which willrelease, the movable section is and allow it to be removed. When thissection is in place the inner bead and parting strip may be replaced andthe 4 and frame together provide spaces between them,

vminimum frictional engagement.

constituting air pockets or cushions which resist wind pressure. Whilethere is a weather-tight juncture between the sash and frame there is aThis reduction of frictional contact is due primarily to the fact thatthe sashes have at their outside edges F rounded beads 4a which ,areadapted during the sliding movement of the sashes to contact with theframe; thus the entire edges of the sash do not at any time contact withthe frame.

Particular attention is called to the manner of securing the panes ofglass 53 in the sashes. A groove 54 may be provided in one bar of thesash to receive a pane of glass, the other three bars of the sash beingformed with integral flanges 55, between which and removable glazinganchor strips 55 the glass' is secured. These glazing anchor strips 55are secured by screws 51 to the sash bars and lie back of integralflanges '58 on the sash bars so that wind pressure is sussashes .A and Bat the overlapping portions of, their meeting rails have notches 5|! atthe ends of the meeting rails and these notched portions- Qf the sashesreceive the parting strip I4. 0n the parting strip a plate 5| issecured. This plate, shown in Figure 2, .is relatively short and v hasbevelled or inclined ends 52' so that when the sashes are togetherthe'plate 5| will bear tightly against the ends of the sashes'and holdthem against rattling or movement. When'the" sashes are partly openedthey will, be free from contact with the plate. 5i and can slide readilyin the frame without unduefriction.

By reason of the construction above described, it will be noted'that wenot only employ a novel arrangement of buck, non-ferrous jamb, headerand sill so constructed as to receive the sliding sashes, but we alsoprovide a novel arrangement of parting strip with continuous resilientweatherstrips therein which are housed in the parting strip, and thespecially designed frame construction provides flat riding surfaces forthe rollers of the sashes to provide easy operating movement thereof.

While we have illustrated what we believe to be the preferred embodimentof our invention, it is to be distinctly understood that various slightchanges may be made with regard to the form and arrangement of partswithout departing from our invention, and hence we do not-limitourselves to the precise details set forth but consider ourselves atliberty to make such changes and alterations as fairly fall within thespirit and scone of the claims. 7
